Climate change not to blame for all extreme weather: feds

Climate change may not be to blame for all severe weather events, according to a new report from the government's weather and climate research arm.

The National Ocean and Atmospheric Administration said Thursday that manmade greenhouse gas emissions cannot be linked to all severe weather events in 2014. But they were linked to specific events such as cyclones off the coast of Hawaii and wildfires.

Many scientists believe that the emissions are causing the Earth's climate to warm, resulting in more severe weather, droughts and flooding.
